Hi blicero,

Focusing on studies and empirical evidence can be a sidetrack. First, trust your inutition. Second, trust successes and experience of other people. Third, trust studies.

Lab tests, while useful at times, remove the human aspect of therapies. How a therapy ultimately affects a vial or test tube is different than how it would effect a person.

With all of that said, I have heard fantastic things about saunas and sweating in general from many people, including many wise ones. I have been using clay baths to draw out mercury and they have helped me a lot. I would recommend saunas but I would recommend clay baths even more since they have helped me.

Good luck with everything
